Support my work
www.buymeacoffee.com/abhishekprd Hi Everyone, We are at Day 14 of our DevOps course and In this video, We will learn about Configuration Management using Ansible.
We will also try to understand why is Ansible better than other configuration management tools like Puppet and Chef.
If you like to take a look at more Ansible Interview Questions. Do take a look at this previous video on our channel.

At first system administrator used to do upgrades, secure patches and installation on 100s of servers using shell script that had to loop over all 100s of servers. With cloud( micro service architecture) no. of servers increased and the compute/resources had decreased. Earlier we had to take care of distribution of OS(alpine, ubuntu), so the script might not work. To solve this configuration management came into picture. Puppet, chef and Ansible . Why Ansible over others? Ansible is much a push mechanism model. Write Ansible script at one instance and update all the worker nodes. Ansible is agentless, just put DNS or ip adress of servers in inventory file and have ssh password-less authentication configured, along with python3 installed by default in Linux distros. 2. Ansible also has feature of dynamic inventory. If you are creating 100s of servers in AWS cloud, Ansible will automatically detect new server. 3. Support both Windows, AIX and Linux all distros 4. Ansible is pretty simple, uses simple yaml manifest.

[@randomavghuman]

one thing i really like about your videos is that it gets me interested in the topic, and its interactive , i always try to answer the interview questions in my head like i would in an interview. it helps me with recollection of concepts

[@paragvade]

Notes of this video- Scenario- System admin has to configure 100s of servers, each with different OS like Ubuntu, CentOS, Windows. Tasks include updating OS, security patches, default installations like git, databases on servers. Issue- Doing this manually on every server is difficult. Hence, scripts were used. Powershell scripts for windows machines, other shells for Linux machines. Even in Linux machines, scripts varied based Linux flavours and type of script (bash, zsh, tsh, etc). This script will then loop over all servers to perform configuration tasks. With cloud and micro service architecture adoption, number of servers have increased further. Hence, even scripting approach is not very efficient. This led to concept of configuration management. Various tools are used for configuration management. Puppet and Chef were pioneering tools while Ansible, developed by Red Had is most popular. Why Ansible over Puppet? 1. Puppet = Pull mechanism, Ansible= Push mechanism. Eg. Managing 10 EC2- Write ansible playbook and push to all 10 EC2 2. Puppet uses Master-Agent architecture- Have to create Master server and configure all 10 EC2 as agents. Ansible is agentless. Write only ip/dns of machine in inventory file and have passwordless authentication enabled. In case of dynamic demand, auto-scaling is possible by changing inventory file. Even better- 'Dynamic Inventory' feature auto detects demand- doing away need to change inventory file. 3. Support for Windows is better in Ansible than Puppet 4. Ansible Playbook is written in YAML which is widely used. Puppet configuration is written in Puppet language. Issues with Ansible 1. Support for Windows is still not seamless 2. Debugging is not easy. Can run ansible in debug mode but debugging logs are not easy to understand. 3. Performance issues- when managing thousands of servers Enjoy!

In AWS while creating EC2 instances - we can give some configurations right? So using ECS which has cluster of EC2 instances or something, can't we do the configurations?? Should Ansible be used? Also in Puppet when you are giving multiple slaves - so if 1000 machines are added. you go and add all the 1000 again in the master file?
